modelZoneHVAC
Thermal zone for HVAC based on 5R1C network
Extends from Zone (Thermal zone based on 5R1C network).
Information
This models is identical to Buildings.ThermalZones.ISO13790.Zone5R1C.Zone, except that a mixing volume is added for integration of HVAC systems based on fluid models. Latent heat gains are also considered.
